Problems solved by technology
[0004] Since the front end beam of the underframe is mostly made of aluminum alloy, when installing the self-tapping screw sleeve, it is necessary to strictly ensure that the direction of entry is perpendicular to the end face. It is difficult to control the on-site operation, and it is easy to cause the threaded hole of the front end beam of the underframe to slip. ; During the later disassembly and maintenance of the anti-climbing device, it is also very easy to cause the threaded hole of the front end beam of the chassis to slip
Once the wire slip occurs, the self-tapping threaded sleeve will not be fastened to the front end beam of the chassis, and it is difficult to repair

Embodiment Construction
[0021] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention but not to limit the scope of the present invention.
[0022] figure 1 It is a schematic diagram of the decomposition structure of the existing anti-climber. It can be seen from the accompanying drawings that the anti-climber 2 is fixed on the end beam 1 at the front of the chassis through the installation bolt 3, and the end of the installation bolt 3 is connected by a self-tapping screw sleeve 5, which is easy to slip Silk, and once the silk cannot be repaired, the use is limited and it is very inflexible.
[0023] figure 2 It is a schematic diagram of an exploded structure of the present invention. It can be seen in conjunction with the accompanying drawings that the installation structure of the subway anti-climber 2 is used to...

The invention relates to a mounting structure for a subway anti-creeper. The mounting structure is used for connecting the subway anti-creeper with a front end beam of a chassis of the subway; the mounting structure comprises a plurality of mounting base plates; the mounting base plates are fixed in the front end beam of the chassis; the anti-creeper is fixed with the front end beam of the chassis through a plurality of fasteners; and the fasteners all penetrate through the mounting base plates. The mounting structure is convenient to use; and more threaded connection contact areas can be supplied to mounting bolts for mounting the anti-creeper by the mounting base plates, so that the anti-creeper can be more firmly mounted, and the sliding of the anti-creeper and the front end beam of the chassis can be prevented.
Description
technical field [0001] The invention relates to an installation structure of a subway anti-climbing device, which belongs to the field of vehicle body design for urban rail transit vehicles. Background technique [0002] At present, the connection between the anti-climbing device of urban rail transit vehicles and the front end beam of the underframe is mostly connected by bolts and self-tapping screw sleeves. figure 1 shown. [0003] This structure requires pre-installing self-tapping threaded sleeves on the front end beam of the underframe, and then installing the anti-climbing device on the front end beam of the underframe through installation bolts and washers. [0004] Since the front end beam of the underframe is mostly made of aluminum alloy, when installing the self-tapping screw sleeve, it is necessary to strictly ensure that the direction of entry is perpendicular to the end face. It is difficult to control the on-site operation, and it is easy to cause the thread...
